R and s compounds
WebbClaim: For r, s positive integers, the number n = r 2 + 2 r s + s 2 is composite. Proof: We must exhibit numbers u and v with the property that u v = n and u ≥ 1 and v ≥ 1, and must also show that n > 1. Basic algebra shows that r 2 + 2 r 2 + s 2 = ( r + s) ( r + s). Let u = r + s and v = r + s. Then the previous equation shows that n = u v. WebbExample #2: Determine priorities for the following chiral center. Step 4: If the last priority group is in the back, then trace a path from highest to lowest priority. - Clockwise = R, …
